The root x = 1 has multiplicity 3 for the function f(x)=x^3-x^2-x+1. True or false
Ostrovityanka [42]
X^3 - x^2 - x + 1 = 0
Plug in x = 1:-
1 -1 - 1 + 1 = 2 - 2 = 0  so x =1 is a root.

If it has multiplicity 3 then  the function will factor to (x - 1)^3:-

(x - 1)^3 = (x - 1)(x^2 - 2x + 1) =  x^3 - 2x^2  + x - x^2 + 2x - 1 
             
 =  x^3 - 3x^2 + 3x - 1  so it is FALSE

What is 732-368 equal to
Gemiola [76]
Answer:
364
732
- 368
_______

To find 2-8 you’ll have to take from the 3 in 732 so the three becomes 2 and the 2 becomes 12 so it is now 12-8 which equals 4

73(2)2(12)
- 368
_______
4

The same process for 2-6 so the 7 becomes 6 and the 2 becomes 12
12-6=6

7(6)3(2)(12)2(12)
- 368
________
64

The last step is 6-3 which is just 3
So your answer is 364
